> Sometimes push down sql doesn't work in Cassandra database because most of the time filtering only works on petition key or index column.   For example, it won't be possible to apply "IN" clause on non-petition key column.  Therefore, I suggest if push down sql fails to execute, I would like to see Teiid to the filtering using Teiid in-memory engine.  Thanks.
